android app: expand and collapse folders in the folder list

[4WoofGrrrr]

Like many others, I have been using Thunderbird on my desktop for many years. More than 20.

I tried the Android version (I previously tried its K-9 precursor) and I am quite disappointed.

There is one missing feature that is an absolute deal-breaker for me: You cannot expand and/or collapse
folders in the folders list. Every one of my folders is displayed in one very long list.

Thanks for submitting an idea to the Mozilla Connect community! Your idea is now open to votes (aka kudos) and comments.

This isn't a "new idea", Jon. People have been discussing it for ten years:

Like OP and countless others, I refuse to use a mail client on Android where you can't COLLAPSE YOUR FOLDERS. It's genuinely unbelievable that nobody has implemented this in a decade. I made a mozilla account just to make this comment. Unbelievable.

@csXRsKyd thanks for attaching these other links — I'll highlight it to the Thunderbird team so they can see this request has even more context than this thread on Connect.

I'm writing because it's astounding to me that this is still an issue. 

The display of subfolders on Thunderbird is incredibly unwieldy. Right now, there is no way to collapse subfolders.

Instead of a neat tree, where the user can collapse or open subfolders, you have a giant mess, e.g.:

Folder1
Folder1.Case1
Folder1.Case2
Folder1.Case3
Folder2
Folder2.File1
Folder2.File1
Folder2.File1
Folder3
Folder3.Item1
Folder3.Item2
Folder3.Item3

And so on. I happen to organize case files, organization files, and intermediate files in separate folders with many, many subfolders.

This means that if I want to access a subfolder under Folder3, I may need to scroll and scroll until I find the subfolder I want. It would be much faster if I could collapse Folder1 and Folder2.

The current set up is ugly and unwieldy. I don't understand the logic of preventing users from collapsing parent folders.

Please, for the love of God, add this function soon. Everything else about Thunderbird for Android is magic.
